Should we close
the existing ramps to Hayden Island that are too close to the bridge
and provide a new access through the Marine Drive interchange?
|
Description
|
|
Move the access to Hayden Island to reduce weaving and merging problems
on I-5, without building new road capacity across the Columbia River.
Access to and from Hayden Island via Marine Drive interchange would
be on a new bridge between Marine Drive and Hayden Island. |

Transportation
Performance
|
- Columbia
River bridges remain the principal bottleneck in the corridor;
but minor improvements in traffic flow and safety on I-5 would
be realized by eliminating the existing weaving and merging
problems associated with Hayden Island interchange.
- Even with
this improvement, Marine Drive interchange remains significantly
overloaded. Would require major reconstruction of interchange
to avoid impacts to heavy volumes of freight traffic and other
vehicles accessing I-5 at Marine Drive.
- Requires
out of direction travel for trucks and autos traveling between
Clark County and Hayden Island.
